Architecture of the SOLiD ECC encoder. The architecture of the convolutional code for the SOLiD ECC consists of two streams. The nucleotide sequence a1,a2,… is passed through the encoder, progressing one position at a time, and the color obtained from the additions and multiplications indicated is emitted from each stream. The top ‘color stream’ is that produced by the two-base-encoding chemistry and the bottom ‘SOLiD ECC stream’ is punctured so that only every fifth color member of the sequence is used.
